What did Peter McCullough say about COVID vaccines, SV40 and cancer?

Peter McCullough said he is greatly concerned that COVID vaccines tilt people toward cancer through several mechanisms at once. He cited a multi-hit hypothesis paper by Bustos in Cureus and a review by Brown oncologist Wafik El-Deiry that he said counted 66 papers. He said labs including Kevin McKernan's found an SV40 promoter sequence in the Pfizer and Moderna shots, and faulted regulators worldwide for never testing the vials.

• McCullough said the mRNA can impair DNA repair and the spike protein can interfere with the P53 and BRCA tumour-suppressor systems.
• McCullough said a 2025 Time magazine cover on rising cancer in young people never considered the pandemic or the vaccines.
• McCullough said SV40 contamination of polio vaccines decades ago led the Institute of Medicine to say later cancers could not be ruled out.
